ROS integration test updates

Doc updates for

• Integration tests for external modes PX4-Autopilot#22494.

We can also move the library integration tests into a separate page under test_and_ci.

We can also move the library integration tests into a separate page under test_and_ci.

I think that makes sense, and cross link.
The doc also needs more clarity on how it works in CI, and links to the tests in github.
My assumption (?) is that eventually this will become the infrastructure to write tests for PX4 systems that use both a companion computer with ROS and PX4 - in other words I write a new mode that does stuff, this allows me to test it. Is that valid?

I think we need these to have a parent doc "Integration Testing". Thoughts?

Yes it could be. How that would look like exactly isn't clear to me either though. Important will be that the tests run fast enough so we can have many.

@bkueng I've added structure to the integration tests part as discussed, moving the ROS1/MAVROS based tests into a new doc and clearly marking as deprecated.

We really do need that "Integrated PX4 and Companion" test story to be fleshed out. Fortunately I'm only here for my good looks, so someone who knows what they are doing will have to sort that out.

Anyway, can you please sanity check this and if you're OK with it we can merge when your autopilot PR goes in.

You're just a bit too quick, it will happen eventually (I hope :). We barely even have some setpoints defined, and even less modes.

Thanks. Ready when you are!
